Geenen-ooe SPECIFICATION forming part of Letters Patent No. 775,697, dated November 22, 1904.

i Application .led dniy 25, 1904.A Serial No. 218,099- *No mndcin ain, Hartford county, Connecticut, have iny vented certain new and usei'ul Imprvements in Grease-Cups. of which the following is a full, clear, and exact description.

My invention relates to lubricators, and particularly to grease-cups.

The object of my invention is mainly to provide a simple and effective construction in a grease-cup whereby the grease may be put undervpressure and fed thereby through a discharge pipe or pipes to'any desired destination. The construction is also such that by a telltale means the user can readily see Whether pressure. is being applied to said grease. These and other advantages will be better appreciated froman examination oi the accompanying drawings and a'reading ot' the following specification.

In the drawings, Figure l is a side elevation of my improved grease-cup. Fig. 2 is a vertical section. Fig. 3 is a plan view.

The grease cup or receptacle proper is pret erably formed of two parts-topwit, an external shell A, 'having a discharge pipe or pipes B B, andl a removable internal shell A. By

i removing the latter the user may more readily iill the cup with grease. The sections A A of the grease-receptacle may be suitably connected or disconnectedwfor example, by

means of a screw-coupling, as shown in Fig. 2. Mounted within the receptacle is a plunger I), 'provided with a handle D', yby means of which the same be may raised or lowered. The

plunger D is preferably threaded externaliy and hollow and is provided at its lower end with a yielding face-plate D2, which closely lits within-the casing A. The face-plate D2 is connected to the lower end of the plunger D, preferably by means or' guide-studs'D3 D3. Between the lower end of the plunger D and "he face-plate D2 a spring or springs Di D4 are located, Ytending to press the faceplate D2 downwardly.

D5 is a rod connected with the face-plate D2 passing out through the hollow shank of the plunger D, so as to be exposed tothe view of the user. A suitable ball or telltale D may be located at the outer end ot' the rod D,

The opera tion of the apparatus is as Follows: The handle D may be turned until the plum ger and face-plate DL are drawn upwardly to the limit of their excursion. The inside casing Af is then filled with grease. The casing A is then returned toits fixed position in thc external casing A.. The handle D is then turned so as to move the plunger downwardly, causing the face-plate D2 to bring up against the grease and press the same toward the discharge pipe or pipes B B. The continued rotation of the .handle 'D' compresses the springs D4, the face-plate D2 being checked by the presence of the grease below the same. '.Ihe'checking of the face-plate D2 causes the telltale DG to rise above the position indicated in Figs. l and 2, so that the user may readily observe whether the pressureof thesprings D4 is being applied to the grease. As the grease is consumed the face-plate D2 moves down, maintaining prcssureuipon the grease until the said plate D2 has reached the limit of its downward excursion relativelyto the part D. Nhen this occurs, the ball D6 will assume the position indicated in the drawings Figs. 1 and 2, and the user can readily see that it is 4incumbent upon him to again put the springs D4 under compression. v

In Fig. 2 I have shown in dotted outline the position of certain parts when screwed part way down.

I have shown and described one form ofthe apparatus,.which it is obvious may be modied in a variety of ways without departing from the spirit and scope of my invention.

Wha-t I claim isHH 1. In a device of the character described, a

grease-receptacle having a discharge-outlet leading therefrom, a manuallynnovable plunger in said receptacle, a yielding face-plate carried thereby within said receptacle,a spring for causing' said face-plate to move independ entiy of said plunger toward and against a body of grease within said receptacle, the movement of said plunger toward said faceplate compressing seid spring, und fr telltale l 3. ln e device of the character described, e

grease-receptacle comprising en external ces? ing, an internal caslng demehebly carried thereby, A hollenv plunger screw-threaded 1n the closed end ol' seid internal casing' and arranged to be moved up and down therein, a face-plete, guide-pins connecting said faceplate WiL-h Seid plunger seid face-plete being longitudinallj,v Vmovable independentlyof said plunger, e spring arranged between said plunger and said farce-plate for normally projecting said face-plate away from' said plunger, 'a telltale device carried by seid fece-plate, said telltale device projecting through seid hollow plunger und exposed at its outer end, substantially as described.
